Customers who have a bank account with certain companies have been alerted that their provider could be "leaving open doors for scammers" to exploit them when they bank online.
A study carried out by consumer experts at Which? and security experts at Red Maple Technologies looked at 13 of the biggest account providers to assess their security when it comes to online and mobile banking. The assessment looked at four key categories - login, encryption, account management, and navigation and logout - to see which banks have the best protections in place.
Virgin Money scored the lowest overall for both online and app banking. Which? also expressed concerns over TSB, which fared second-worst in the study for app banking, and Nationwide, which came above Virgin at the bottom for online banking security. At the other end of the scale, Starling Bank received the highest score for online banking while HSBC came out on top for app security.
